• DO NOT force the equipment controls past their stopping points.• DO NOT leave the equipment activated during breaks in operation.• DO NOT store the equipment with the batteries installed.• Thoroughly clean and dry each item before placing them into the storage

case.

NOTES:

• Do not test the device in daylight conditions for more than ten (10) minutes, even with the daylight filter/ lens cap on.

• The purpose of the built-in IR illuminator is to provide additional illumination when necessary while viewing scenes at close distances (up to 3 meters).

• The equipment requires some ambient light (moonlight, starlight, etc.) to operate.

• Performance of the device in night-time conditions depends on the level of ambient light in the environment. Please remember the following:

– The level of ambient light is reduced by the presence of clouds, shade, or objects that block natural light (trees, buildings, etc.).

– The equipment is less effective when operated in shadows and other darkened areas.

– The equipment is less effective when operated in rain, fog, sleet, snow, dust or smoke.

– The equipment will not “see” through dense smoke.

1 GENERAL INFORMATION

1.1 SYSTEM DESCRIPTION

The AGM NVG-40 and NVG-50 are a dual-channel night vision systems. The NVG-40/NVG-50 utilizes the principle of intensification of the residual light that is reflected from the surrounding objects. The optical system of the unit consists of two monocular channels, each consisting of a lens, an image intensifier tube (IIT), and an eyepiece. This device operates with a single gain control knob for both channels. Each unit allows for vertical adjustment (using the head or helmet mount), fore-and-aft adjustment, objective lens focus, eyepiece focus, and interpupillary distance adjustment. The binoculars are equipped with an infrared (IR) light-emitting diode (or illuminator) to provide additional illumination for reading a map. The binoculars are also equipped a low battery indicator, a bright light cut-off system indicator, and IR illuminator indicator in the field of view of device.
